Also, you really don’t want to play baseball (or hardly any other ball sports) with such bad vision, even if glasses offer awesome correction.

The refraction difference between the front facing direction versus sight out of the corner of your eye outside of the lens range is rather extreme and causes significant shear and even double vision of sorts when looking near the edges of the glasses.

Imagine seeing a baseball coming your way out of the corner of your vision, and you see a ball both inside the corrective lenses, and also see a ball offset outside of the range of the lenses. Depth perception goes right out the window, and you can almost be guaranteed to get smacked in the head with the ball.
